Add updateInfoPayload implementation

[samholmes]

This will update the networkInfo with the infoPayload data. A couple
questions remain:

1. Should the infoPayload update more than the networkInfo for a plugin?
2. Is it important for the network adapters to be immediately recreated
   when the config changes, or is it okay for this to occur on engine
   restart?
